MINERS FUSE PLIEBS.

Application filed June 15,

To all whom it concern:

Be it known that we, JOHN YOUREK, J12, and STEPHEN YOUREK, citizens ofthe United States of America, residing at Thayer, in the county ofSangamon and State of Illinois, have invented certain new and usefulImprovements in Miners Fuse Pliers, of which the following is aspecification.

This invention relates to miners tools, and has special reference to aminers fuse plier.

One important object of the invention is to improve the generalconstruction of devices of this character.

A second important object of the invention is to provide an improvedform of fuse plier wherein novel means is provided for splitting thefuse, cutting it oil? and splitting it at the knotted part thereof.

A third important object of the invention is to provide, in one tool.means for cutting and splitting the fuse either at its end or in theknotted part. means for crimping the dynamite caps used therefor, andmeans l for cutting the paper used by miners to wrap fuse ends andcharges of powder and the like.

WVith the above and other objects in view as will be hereinafterapparent. the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawings and specificallv claimed.

In the accompanying drawings like characters of reference indicate likeparts in the several views, and:

Fig. 1 is a side elevation of a pair of fuse pliers constructed inaccordance with this invention, one position of the pliers beingindicated in full lines, and a second position being indicated in dottedlines;

Fig. 2 is a cross-sectional view through the handles of the pliers intheir closed position, the view disclosing the can crimping device;

Fig. 3 is a detail perspective view of the lower jaw of the pliersshowing the parts separated and;

Fig. 4 is a transverse section taken through the jaws in their closedposition.

In the embodiment of the invention herein illustrated, there is provideda pair of members pivotally connected at 10, and one of these membershas a jaw 11 and handle 12, while the other is provided with a jaw 1923.Serial N0. 645,623.

13 and handle 14. The jaw 11 is longitudinally channeled as at 15, andcarries a cutter blade or knife 16 which extends longi tudinally of thejaw and upon closing of the pliers will be in a space 17 formed in theopposite jaw. The side walls of the jaw 11 are transversely grooved asat 18, the groove intersecting the knife blade so that fuse may bereceived therein and cut by said knife blade. The outer end of the jaw13 is laterally reduced on each side as at 19, and also is cut away atthe bottom to provide a shoulder 20. This rabbet 20 receives a plate 21forming the base or attaching means for a pair of spaced side walls 22.which are so arranged that they fit closely against the sides of thereduced ends 19.

In order to prevent longitudinal movement of the member having the sidewalls 22, the plate is apertured for the passage of a suitable screw 25which passes through the plate 21 into the underside of the jaw 13, asshown in Fig. 1. Projecting toward each other from the side walls 22 areflanges or concave seats 26 which engage over the top of the reducedportion 19, and are spaced to provide a slot 27 wherethrough the knife16 may pass. On one of the handles, as 12, there is provided aprojecting portion having an arcuate recess 28. while on the otherhandle is an opposed crimping member 29 so that after a cap has beenfitted. on the end of a length of fuse, it may be placed in the socket28 and crimped by the member 29. The extremities of the handle portionsare suitably arranged for other operations, and to this end theextremity of the portion 14 has a section 30 formed of brass, cop per,or the like, which is a non-sparking metal under the conditions ofminers use, and the end of this section is secured to the body of thehandle as by dovetailing 31. The other end from the dovetail of thesection 30 is formed with a sharp edge 32, so that it may be used foropening powder cans and the like with safety. The other handle 14 isprovided with a sharp cutter roll 33 which may be used for cutting thepaper commonly used by miners. It will be noted that the upper sides ofthe flanges 26 are concave in form so that they can properly support afuse end for splitting by the blade 16.

The knife or blade 16 and the shoulder 19 means for cutting a length offuse, in the blade and slot means for splitting the fuse end, in theslotted jaw means for splitting the knotted portion of the fuse, itbeing common to knot the latter before inserted in the powder. Also thistool provides means for opening powder cans with safety,

means for crimping caps and means for cutting paper.

There has thus been provided a simple and efficient device of the kinddescribed and for the purpose specified.

It is obvious that minor changes may be made in the form andconstruction of the invention without departing from the material spiritthereof. It is not, therefore, desired to confine the invention to theexact form. herein shown-and described, but it is desired to include allsuch as properly come within the scope claimed.

Having thus described the what is claimed as new, is:

1. A miners fuse pliers consisting of a pair of pivotally connectedmembers each having av jaw at one end and a handle at the other, one ofsaid jaws being provided with a longitudinal cutter blade and the otherjaw being provide with a. longitudinal slot to receive said blade uponthe jaws being closed, said slot-provided jaw being reduced at its outerend, and a second slotted jaw removably mounted on said reduced end.

2. A miners fuse pliers consisting of a pair of pivotally connectedmembers each having a jaw at one end and a handle at in venti on,

the other, one of said jaws being provided' with a longitudinal cutterblade and the other jaw being provided w1th a 10ngitudi nal slot toreceive said blade upon the jaws being closed, said slot-provided jawbeing reduced at its outer end, a removable sl0tted membe having asupporting plate engageable with the back of the slotted jaw andprovided with spaced portions ar ranged parallel to and on oppositesides of the slot, said spaced portions fitting closely against thesides of said reduced portion of the jaw.

3. .A miners fuse pliers consisting of a pair of pivotally connectedmembers each having a jaw at one end and handle at the other, one ofsaid jaws being pro videdwith a longitudinal cutter blade and the otherjaw being provided with a longitudinal slot to receive said blade uponthe jaws being closed, said slot-provided jaw being reduced at its outerend, a double member having a supporting plate engageable with the backof the slotted jaw and provided with spaced portions arranged parallelto and on opposite sides of the slot, said spaced portions fittingclosely against the sides of said reduced portion of the jaw, and pro-VlClBClWltll opposed internal shoulders fitting over the top of thereduced portion of the jaw and spaced to permit passage of the firstcutter blade therebetween.

.4. A miners fuse pliers consisting of a pair of pivotally connectedmembers each. comprising a jaw portion and a handle portion, one of saidjaws being provided with a longitudinally extending single cutter blade,the other of said jaws being provided with a slot for receiving saidblade and supporting a removable pair of longitudinally extending fusesupporting members at its end, a cap crimper between the handleportions, and a roller journaled in the end of one handle portion.
